If anyone wants it, Grandpa has a brochure PDF from 1998-1999 showing Watchtower leadership, participating with other religious organizations such as mentioned above.
The brochure came from "Comments From The Friends" and it is still there.
I was only 3 or 4 years old the first time the Watchtower got involved with these groups.
You go here and look to the left. Under 1999 Jan-Mar, look for (Dracula--Mormons--Moonies, New Age, etc, and the brochure is still there. I can send you a PDF if you want.
